TANK.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed October 24:, 1905. Serial No- 284,185.

To all whom it may concern.-

Be it known that I, ISAAC ANDERSON, a citizen of the United States, residing at Mc- Oabe, in the county of Yavapai, Arizona Territory, have invented a new and useful Tank, of which the following is a specification.

This invention relates to tanks.

The object of the invention is in a novel and practical manner to dispense with the ordinary metallic bottom such as is commonly employed in connection with metallic tanks and in lieu thereof to employ a bottom made of concrete which shall be combined with the body of the tank in such manner as to be positively held against possibility of separation therefrom or from becoming loosened by jars or vibrations.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a composite tank, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in perspective, partly in section, of a tank constructed in accordance with the present invention. Fig. 2 is a vertical sectional view through'the tank shown in Fig. 1. Fig. 3 is a vertical sectional view through a portion of the tank, showing a slightly-modified form of the invention.

Referring to the drawings, 1 designates the body of the tank, which is herein shown as constructed of sheets of metal assembled by rivets, although this is not essential, as the body may be constructed in any other manner and still be within the scope of the invention. Any suitable sheet metal may be employed, such as sheet-steel, galvanized iron, or any other metal adapted for the purpose.

The outer edge of the frame is reinforced by an angle-iron annulus or flange 2, which maybe secured to the tank either by rivets, as shown, by solder, or otherwise. By constructing the reinforce of angle-iron the maximum of strength with a minimum of weight for causing the tank to resist any tendency to yield under strains will be secured.

The bottom 3, which constitutes the gist of the present invention, is composed of a suitable concrete and may be of any thickness and is extended around the exterior of the bottom portion of the tank to form a reinforcing-hoop 4 to strengthen this portion of the tank from any tendency to yield and to insure a liquid-tight juncture between the body and the bottom 8.

Under some conditions where the tank will be subjected to unusual strains, as from being frequently moved, or from any other causes, the bottom 3 may be reinforced by bars 5, as shown in Fig. 3, which are shown as interlaced, but may be otherwise disposed, and the terminals 6 of which project through the bottom portion of the body and the hoop 4, and thereby prevent the latter from becoming disconnected from the tank-body. Instead of having the reinforces 5 interlaced, as shown, but one series of reinforcing-bars may be employed, all of which may extend in the same direction, or two series may be employed, one superposed above the other and not interlaced.

By the manner of combining the bottoms with the tanks, as herein shown, a more stable juncture is secured and one that will be thoroughly effective in causing the tank to be liquid-tight.

The advantages accruing from the employment of a cement bottom from the ordmary metal bottom are that it is initially cheaper and in case of injury can be readily re aired, for should the bottom become crac red or otherwise damaged it may be quickly and easily repaired by flowing cement into thefractured portion.

Having thus described the invention, what is claimed is- A tank comprising a metallic body portion and a concrete bottom, a concrete reinforcing-hoop extending around the exterior of the body, and reinforces included in the bottom and projecting through the side walls of the body portion at said hoop.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

ISAAC ANDERSON.
